Whats in the process for converting them? Do you have a program to do it or....
I use FS2XPlane, by Jonathan Harris (aka Marginal):
http://marginal.org.uk/x-planescenery/index.html (there's no other tool). Once converted, I use World Editor (WED:
http://scenery.x-plane.com/tools.php) to reproduce the airport's hard surfaces in an X-Plane-friendly way, and OverlayEditor to move and place objects should it be necessary (also from Jonathan Harris).
Use DDS graphics for X-Plane 9 only scenery output, PNG for slower but v8 &v9 graphics compatibility. Note, DDS graphics can be a bit harder to handle if you need to edit an object.
